## Issues

### Warnings (9)

#### Thin content (low word count)

- Rule: `content.thin` · Category: Content · Occurrences: 3

- [https://www.fw4k.org/](https://www.fw4k.org/) — 113 words
- [https://www.fw4k.org/copia-de-support-us](https://www.fw4k.org/copia-de-support-us) — 137 words
- [https://www.fw4k.org/support-us](https://www.fw4k.org/support-us) — 152 words

#### Hero/LCP image is lazy-loaded (loading=lazy delays LCP)

- Rule: `images.no_lazy_lcp_candidate` · Category: Performance · Occurrences: 1

- [https://www.fw4k.org/about](https://www.fw4k.org/about) — the likely hero/LCP image (a00911_ae0df2d598f541b7817ee94abe8f5df6~mv2.png) has loading="lazy" — Google explicitly warns against lazy-loading the LCP image, because it delays the fetch until layout completes. Remove loading="lazy" from the first significant image and add fetchpriority="high" instead.

- [https://www.fw4k.org/copia-de-support-us](https://www.fw4k.org/copia-de-support-us)

- Rule: `perf.render_blocking` · Category: Performance · Occurrences: 4

- [https://www.fw4k.org/](https://www.fw4k.org/) — 2 render-blocking <script> in <head> (add defer/async or use type=module)

#### Likely hero image lacks fetchpriority=high

- Rule: `images.hero_no_fetchpriority` · Category: Performance · Occurrences: 2

This is a low-severity nudge; verify the flagged image is actually your LCP element.
- [https://www.fw4k.org/support-us](https://www.fw4k.org/support-us) — the likely hero/LCP image (a00911_72d0a04232734c358367d1991538eb92~mv2_d_2560_1440_s_2.jpg) has no fetchpriority="high" — adding it tells the browser to fetch the hero earlier in the waterfall, reducing Largest Contentful Paint.

- Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 3
